HELP! Strange problem with Starhub Fiber but not M1 Fiber, come hear it

As above,



Setup (Previously using M1 Fiber)

ONT > HomePlug(Sinoji) > Router(Asus AC56) > PC

Speed test at PC 100mbps



Setup (Same as before but now Starhub Fiber)

ONT > HomePlug(Sinoji) > Router(Asus AC56) > PC

Speed test at PC 1 to 3 mbps only



Change setup

ONT > Router(Asus AC56) > HomePlug(Sinoji)> PC

Speed test at PC 100mbps



Any logical explanation? Starhub issue?
